Large Function Combined With Sumif

I know how to use the large function when looking for a specific criteria as the example below illustrates:

Code:
=IFERROR(LARGE(IF('2012'!$D$1:$D$7="Green",'2012'!$C$1:$C$7),1),"-")

What I'm trying to do is take this one step further and not only find the nth largest numbers in a set of data based on a particular criteria, but also sum those numbers because they repeat in a table: for example a sample table is below:

Account Accout # Store # channel $ sales
A 1000 10001 green $100
B 1001 10011 green $230
A 1000 10002 green $120
C 1002 10021 brown $145
A 1000 10003 green $100
D 1003 10031 red $20
B 1001 10012 green $50

So what I'm basically attempting to do is bring in the nth largest accounts within the "green" channel. Now if these were the top 5 stores I was looking for, the formula from above would suffice. However since this deals with accounts and the account # repeat I need to bring in the total sum of those repeating accounts instead of just one of the unique stores. So if I was seeking the largest account (NOT store) within the "green" channel the correct values this formula would be:

Account A $320

I would imagine we would need to combine a sumif with a large function or maybe involve sumproduct somehow.
